Manufacturing Quality Control of 4-BROMO-2-DIFLUOROMETHYL-1-FLUOROBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent residues are vaporized in sealed vials and quantified via GC-FID using calibration curves. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column and quantification via conductivity response. |
| Acid-Base Impurities | Acid-Base Potentiometric Titration | Titration with standardized NaOH or HCl to detect titratable acidic or basic species by pH endpoint. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample is ignited at 700-800 C after sulfuric acid treatment; residue mass reflects inorganic impurities. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral components in solution. |
| Appearance | Visual Inspection (in solution/solid state) | Assessment of color, clarity, and physical state against established reference standards under controlled lighting. |
| Bulk Density | Tap Density Measurement (ASTM D1895) | Determined by measuring mass per unit volume after standardized mechanical tapping of a powder sample. |
